FAS'lENING-INSERTING MACHINE.

Application filed Jiu This invention relat to fastening inserting machines and is herein illustrated as eluhodied in a machine particularly designed to insert.metallic fastenings such as nails into trunks or other hulliy objects during the marmfacture thereof.

Many trunks as n1ainifactured at the proscnt time consist of wooden looxes covered on the outside with a heavy fabric or other sheet material and reinforced at the edges and at intervals across the surfaces of the trunks with strips of u'ictal v tihrehoard, wood, or other suit-able strengthening material. These reinforcing); strips are ordinarily secured in place by stout nails more or less closely spaced and prior to the present invention. usually inserted hy hand.

Accordingly it is an object. of the present invention to provide a machine particularly adapted to insert fasteningg s into trunks and the l ke during the manufacture thereof.

\Vith this object in view and in order to speed up the insertion of the fastenings, a feature of the invention comprises the comhination in a 't'asteniae; inserting machine having fastening inserting mechanism and a (vi-operating work support, of means for operat ng: the fastening; inserting mechanism to nsert fastenings in the work during relative movementof the fastening insertinp; inecl'ianism and the support transversely of the work. In. the ilhiistrated machine the work is held stationary on the work support and. the throat and driver are carried by a head which is moved continuously across the worle, the fastening s being inserted in a row during; the continuous movement of the head.

A further feature of the invention comprises the provision a fastening inserting machine in which the head of the machine and the work have continuous relative movement in a direction transversely of the wo k, of means for loving the nozzle or ether device by which the fastenings are guided to the work in a direction opposite to that of the relative movement of the head and the work so that this relative movement is countciactnd at the instant of the insertion, of each fastening: with the result that the fastenine' is driven nst as it would he if the head of the machine and the work were both at rest. In the illustrated ma- 1922. Sieria1No.573,353. i

chine the fastening inserting instrumentali-f" ties are carried hy a swinging head mounted upon a head arranged for continuous move ment at a uniform speed transversely of the work, the linear velocity of the outlet of the nozzle carried hy thoswingiug head, relatively to the continuously moving head, being, at the time the fastenings are inserted,

equal to the velocity of the continuously moving head but in the opposite direction thereto.

A further feature of the invent-ion co1nprises the provision in a machine arranged to insert fastenings in trunks or other bulky objects and havii'ig means for causing relative n'loveincnt of the fastening inserting instriunentalities and the work, in a direction transversely of the work, of gear shift mechanism arranged to vary the rate of relative movement of the head of the machine and.

the work and thus to vary the spacing of the fastenings inserted into the Work. In the illustrated machine the varying of the speed of n'iovement of the head in no Way affects the speed at which the fastening inserting mechanism is operated or the num her of operations which it performs in a given unit of time so that the distance between adjacent fastcnings varies directly with the rate of movement of the head rela tively to the work. i

In accordance with a further feature of the invention, the illustrated machine coinpriscs a novel organization of fastening inserting" mechanism and co-operating Work presenting and supporting means.

Still other features of the HIVGHtlOILlD- elude the provision of novel stop mechanism and reversing mechanism to cause the head of the machine to stop and to, reverse its direction of movement when it reaches pre determined points in its path of movement across the work. 1

Still. another feature of the invention COHlPliSGS a gage and mechanism for rapidly and conveniently shifting the gagefrom one to the other of two positions upon opposite sides of the point at which the operatino; devices of the machine act upon the work so that the work may conveniently be hedral angle of the work and at predetermined distances from the edge at which those surfaees intersect.

\Vith the abovi and other objects and teatures in view the invention will now be deseribed in eonneetion with the :u(:o|upan viug drawings whit-h illu-strate a practical er;- eniplilieation thereo-t' and pointed out in the subjoined elaims.

For this purpose a pulley is sliding'ly m unted upon the s-hatt: 313. the shalt and the bore ot the pulley being ot' a eontigurat on to rause the pulley to rot: te with the shalt. The hub ol' pulley i2 is journaled in bearing members -l-l ('tll'l'itll by a rod lti l i it and 4-) extending upwardly and rem'wardly upon the head 52 n. belt in (mint-(ts pulley 42 with a pulley fi l serured to a shalt 5; suitably journaled in head 28 and provided with a spiral gear ill meshing with a err-operating spiral gear 5t; mounted upon a shalt 58. the rear extremity of whieh carries a pinion meshing with spur gearing (it) formed about the periphery of the nail pot. riha't't 5'2 earries upon its right, hand extremity (Fig. 53) a ram eo-omratiiie with a blade (12 seeured at (3! to a l ver (iii. the blade (32 l'ieing held in eontart with its ram by a torsion spring tib. lierer till also earries a spring held linger Ttl whirh is thus osrillated by the rotation ot the ra and serves to vibrate the raeeway to assist the feed ol the nails therein.

.lournaled in the head 29 is a can! shaft driven from shalt IH- through a pair ot' beve g ars 86. SR. the former ot whii'h is splined to sl aft 34. Fast upon sha'l't t-tl is a ram it prov d w th a "on tra l; in whitoperates a roll 5); rarried by on end ot a lever '1. the latter in turn bein'r rrrri 'l bv a ltu'hf shatt 96 provided with a slotted arm t in whieh adjustably mounted one end of a link 100. the other end of which is pivoted at 102 to the swinging head 78 so that each rotation of shaft 84 causes a complete oscillation of the swinging head.

rilidingly mounted in ways 101 carried by the swinging head 78' is av block 106 to which is adjustably clampeda driver bar 108. the latter having the driver 76 secured to its lower end and being provided with operating mechanism substantially as disclosed in U. S. patent to Louis Goddu No. 19O 62 l Jan. 21, 1893. Thus the driver is elevated periodically by the operation of a cam mounted upon shaft 84-. and is driven down to insert the fastcnings by spring 110, the latter being connected to the driver bar through lever 112 and link 111.

To control the passage of the nails from the raceway 40 to the throat member 7 1, the machine is provided with a separator carried at the lower extren iity of a lever 122 (Fig. 3) pivoted at 124 to the swinging head 78 and carrying at its upper end a roll 128 co-operating with a cam. track formed upon cam 90, roll 126 being held in contact with the cam track by a spring 128. Thus the separator is operated synchronously with the movement of the throat and with the operation of the driver to cause the delivery of a fastening from the raceway to the throat when the throat is at the right hand extremity of its path of movement, as viewed in Fig. 3, and before descent of the driver to insert the fastenings.

In order to speed up the operation of the machine as a whole, the sliding head 28 is arranged for continuous movement along track 26. To facilitate the insertion of fastenings in the work during the actual movement. 0" the sliding head, the swinging head of the machine is arranged so that at the time of the actual insertion of each fastenin g, that is during substantially that portion of the descent of the driver when it is in contact with the head of a fastening the swinging head 'is moving relat' *ely to the sliding head in. the opposite direction from the nmvement of the sliding head and at such an angular velocity that the linear ve locity of the throat with respect to the sliding head is: equal in extent but opposite in direction to the velocity of movement of the sliding head. Thus though the sliding head continues without interruption in its traversing movement across the work. the fastoning is inserted substantially as it would be if the entire fastening inserting mechanism and the work were both at rest, the swinging movement-of the head 78 counteracting the sliding movement of head 28.

Power for shifting; the sliding head 28 along track 26 is transmitted froi'n shaft 36 by means of gearing which will now be described. A pinion 134 formed integral with a bevel gear 136 is fast on a shaft 138 car ried by sliding head 28 and meshes with rack theclutch 1 12, let-l: is thus tive, a Weight 15- carried in a. bite of a 30. (lo-operating with bevel gear 136 is a. second bevel gear 110 mounted for rotation upon shaft 36 and a-rrai'iged to be driven thereby through co-operat-ing clutch members 1l2 1 1 1 carried by bevel gear 140 and by a sleeve respectively, the latter being splined to shaft 36 and being formed with a groove. co operat-ing with a yoke 116 carried by a rack 118 slidingly mounted in the head 28. Back 1 18 meshes with a gear mem ber formed rigid with a lever so that the rocking of the lever in one direction or the latother will throw clutch. members 112, into or out of operative relation. When rendered inoperachain or cable 156 anchored at one end to the frame of the machine and at the other end to head 28 returns the latter to the left for the commencement of a new. row of fastenings. A limit. stop 155, preferably adjustable, may also be provided positively to limit the movei'nent of head 28 to the leftwhen it is returned by weight 154:.

Lever 150 may conveniently be irtwided with a pair of notches 160 arranged tocooperate with a resilient or spring mounted latch member 161 impositively to hold clutch members 1 1-2 and 14st in or out of engagement during the movement of the head of the machine. As illustrated in Figs. may conveniently be n'ovided with a hand wheel by means of which the slidinghead may be moved manually along the track.

The operating" mechanism for shafts 82, 81 and 36 will now" be described. Carried by L bI'ZIClKBtJ (Fig. 1) attached to column 20 is a motor 17 2 suitably belted to a pulley 17 1 (Fig. 5) loose upon ashaft176 journaled in a change speed gear caning 178 carried by the frame of the machine. Shaft 176 is a continuation of, or is (meratively connected to, shaft 3 1 so that the two rot-ate together. Pulley 174i is formed with a clutch surface arranged for. engagen'ieut with a (-0- operating surface of a clutch member 178, the latter being splined to shaft 176 and pro vided also with a brake surfaceltltl arrai'iged to co-operate with a. stationary brake surface so that shaft 176 may be brought to rest immediately when clutch member .178 is thrown out of driving relation to pulley 171. A stiff con'ipression spring" 182 tends to move clutch member into driving relation with pulley 1H. Carried by the hub of clutch member 178 are a pair of pins 184: engaging a pair of hook upon the upper end of a lever 186' fulcrumed at 188 to a. suitable rigid part of the 'lrame. At its lower end lever 186 is connected to one end of a toggle member the other end of which is connected to a co-operating toggle member 190 pivoted at 192 to a lever 191 fulcrumed at 196 to a stationary part of 3 and l, shaft 138 members formed ill] . operat:o11.

the frame. At its upper extremity lever 194 is provit led with :1 am roll 198 co-o 'ierating with a cam track 200 formed upon a -an1 member carried by shaft 176. Cam tech 200 is provided with a rise 202 o1 such a. configuration that when toggle 189. 191) is st'aightiened it will rock lever 19-! to an ex tent sufficient to cause lever to compress spring 182 and move clutch member 171-; out of engagement with pulley 171- and into engagementwith b 'ake surface 181) to stop the rotation ol shaft 176. \Vhen. however. tog- ;rle 188, .190 broken the passage of rise 202 past cam roll 1% has no cliect atall upon lever 186 or the clutch 11'101nher.

Pivoted at 201 to toggle member is a latch lever 206 provided with a block 208 arranged to co-operate with a lug 21!) formed upon toggle member 183. A compression spring 212 surrounding: a rod 214- and liiearing at one end against the frame ol the machine and at the other end upon a collar carried by the rod tends to straighten the toggle. and when it is once str:i; 'ht ened hlock 20S hearing" against lue' i210 holds it iiositively in. that contl'tion until the left: hand end of lever 206 is swung downwardly as will be hereinafter described.

To permit the open-dive conveniently to stop and start the machine lrom any position in front of it. there is provided a coin trolling" rod 1216 (Figs. 1 and upon which is adjustably mounted a stop E218 arranged in the path of movement of a finger 220 carried by the head 28 of the machine. Rod E2113 is pivoted at its left hand end to a hell crank lever 22:? fulcrumed to a lug or projection 221 carried by the frame of the machine. Bell 0 'ank lever 222 is connected by :1 pin-and-slot connection to a link 2% pivoted at its other OXl'ltH'lll') to lever 206. Thus when rod 216 is shifted to the left, hell crank lever 222 pulls down upon link 2:26 and lever 206. compressing springs 212 and brrakine toggle 188, 190 so that spring 18:2 is permitted to throw clutch 180 into On the other hand, when rod 216 is shifted to the right, lever 206 is permitted to rise under the action of conuwn'ession spring 212 strai 'hteningthe toggle, which is latched in straightened position by the eo-operation of block 208 and lag 210, so that when the rise 202 of cam track fltltl reaches cam roll 198. the straightened toggle will rock lever 186 in a clockwise direction compressing spring 182 and shiftingclutch member 178 from operative to braking position. In order to hold rod 216 in the position to which it is shifted, hell c 11111; lever is provided with a pair of notchn; cooperating with a spring pressed latch member 2:28 which impositively holds it in position. hen. during the traverse of head 28, linger 220 reaches stop 218, rod 216 is moved to the right, thus automatically rendering the clutch im'i 'ierative and tom'iing the machine.

Thus the speed of rotation of hal't 313 and hence the velocity ol travers iue movement ot' head 28 may he varied without changing the speed of rotation of shaft Ill or ot r hajl't 1751. or the rate of insertiou ot' the fastenines. the spacin; ot' the tastenings in the work being corres iondinely varied.

Rigid with pulley lit and hence eontinuously rotated therewith is a smaller pulley 2TH belted to pulley L272 loosely mounted upon shaft 32 and having a hearing in a bracket member carried by the t'rame. t plined to shat't I is a sleeve 2T6 carrying at its left hand end a clutrh 111en1her 27H co-opciz-iting with a clutch surface 381] formed upon pulley 2T2, clutch member .L'To being); sermrated from the hub ol' the pulley by :1 spring washer 252. Normally contacting with the right hand end (11' sleeve 271i is a disk 2S4: engaging a pair ole lugs 286 carried by a yoke 2S8 mounted upon the end of a shalt 2:111 suitably 1ournalcd 1n the :t'rame oi the machine, and provided with :1 handle 292 for the operation thereol'. A spring; 1394 holds disk 284 in e11; ra;5en1ent with lues 286, the spring hearing at its right, hand end upon a collar 21h; fast upon shaft 212.

Lugs 1286 are so arranged that when handle 292 is moved to its extreme right hand position they are rotated slightly past their extreme right hand position so that spring 291 if? compressed and clutch member 2TH is rendered inoperative. \Vheu handle 2512 is moved to its extreme lct't hand position. lugs 2813 are moved tar enough to the le t't to permit spring 294, to force clutch member 2TH into engagement with clutch surface 280 to 2111512 the rotation ol' shaft 32. it will b evident from the toregmii'ie" that shalt 3:3 and consequently the hopper mechanism may be operated continuously whether the taversing and fastening ii'iscrtinn' mechanisms are in operation or not, thus as uring a continuous supply of nails in the raceway.

mechanism may be thrown out of operation while the rest of the machine continues running as may be convenient, for example, in emptying the raceway.

The machine of Fig. 1 is provided with two separate work supports 300 and 302, the former being arranged to support the body or top of a trunk while fastenings are insorted adjacent to an edge between the top or bottom and the side or end, while the latter is arranged to support the body or top of a trunk during the insertion of a row of fastenings along an edge adjacent to a side and end.

Work support 300 comprises a head illustrated as a bar or anvil 304 (Fig. 6) arranged toenter a dihedral angle of the work and carried upon the upper extremity of a pair of arms illustrated'as rods 306 each having a bearing portion journalcd in a bearing sleeve 308 provided with a downwardly extending arm 310. Sleeves 308 are mounted for rotation in vertical planes about a shaft 312, the latter being journaled in a pair of slidingly mounted boxes 3L4. \Vob 24 is provided with a pair of upwardly extending lugs 316 which serve as stops for arms 310, springs 318 tending to hold arms 310 and lugs 316 in contact. Each rod 306 is provided with a counterweight 320 acting in opposition to spring 318 but preferably of a weight not quite sufficient to overcome the action of the spring. This work support may be lowered for the placing of a trunk thereon. and raised into operative position by mechanism which will now be described. Fulcrumed at to the base of the columns 20, 22 is an elongated treadle 324, the rearwardly and upwariilly extending ends of which are connected by adj ustable links 326 with the knuckles of toggles 328, 330, the lower members of which are pivoted to web 24, and the upper mei'nbers of which have bearings in slides 332 (Figs. 6 and 7) vertically movable in ways 334 carried by columns 20 and 22. Each slide 332 is provided at its upper extremity with a seat for a spring 336, the upper end of which bears against a nut 338 adjustable upon athreaded rod 340 carried by box 314. Thus as the toggle is straightened shat and the work support carried thereby will be raised to bring the work into operative position, springs 336 yielding as may be necessary. To insure the positive lowering of the work support when the treadle is released, each slide 332 carries a screw 342 arranged to impinge upon the upper end of box 314 as the slide lowered, pOSltlVtly to push box 314 down as the toggle is broken. A supplemental work support illustrated as a vertically adjustable T-shaped bar 344 is carried by a web 346 connecting sleeves 308 and is at times convenient in supporting a i to the left.

portion of the work remote from bar 304.

Inorder that the work support 300 may' forwardly and the formerly forwardly extending portion 350 extends upwardly as shown in broken lines in Fig. 6. Since the bearings of anvil 304 on rods 350 are arranged in the line of the axes of bearing sleeves 308 about which rods 306 rotate, this may be done without removing the anvil. To facilitate this changing of position, each rod 306 is provided with a spiral gear 353 meshing with corresponding gears formed upon shaft 312 so that as the latter is 1'0- tated rods 306 will move from one position to the other. As shown in Fig. 1, a hand lever 352 is carried'by shaft 312 to facilitate the rotation thereof.

The machine of Fig. 2 and the right hand end ofthe machine ofFig. l are illustrated as provided with a work support arranged to support a body or cover of a trunk for the insertion of fastenings adjacent to the corners between the sides and ends thereof, the work being positioned with its open face This work support comprises an outwardly extending arm 360 mounted for vcrtical'sliding movement in ways illus trated carried by a plate 362 secured to column 22. Attached to the 'left hand end of plate-360 is a downwardly extending sleeve 364 inwhich is slidably carried a knob formed on the upper end of a rod 368, the lower end of which is screw-threaded and carries an abutn'ient 370 for a compression spring 372 surrounding rod 368 and supporting sleeve 364 and plate 360. A pin 373 carried by knob 366 is positioned in a slot formed-in sleeve 364, and limits the relative movement of muses and plate 360. Rod 368 is in turn supported at its lower end by a lever 37 2 fulcrumed at 37 4 to col- .umn 22 and connected by a link 376 with the upwardly extending end of a treadle 378 fulcrumed at 380 to the base of column 22. The upwardly extending end of this treadle and link 376 co-operate to form a toggle which is provided with a spring 382 tending to break the toggle so as to permit the lowering of the work support when the treadle is released. lVhen the treadle is depressed upon the other hand, the toggle is straightened and lever 372, rod 368, spring 372, sleeve 364 and plate 360 of the work support are raised so that the work is held yieldingly against a gage or abutment 384.

Abutment 384 and the corresponding abutment 386 which co-operates with the work support 300 are illustrated as adjustable gages arranged to facilitate the correct presentation of the work to the fastening inserting means. Accordingly abutment or gage 384 is carried by the forward extremity of a pair of rack bars 388, 390 slidably mounted in ways 392, 3% carried by the frame of the n'lachine and meshing with gear segments one. 398 iast upon an inclined rock shaft 400 (Figs. 8 and 5)). ln Fig. 9 gage Z384 is shown in position to present a trunk for the insertion of nails in the position indicated at 41-02. If it is desired, however, to insert nails in the position indicated at. -1, it. necessary to move gage 384 to the opposite side of the Work support 302 from that which it now occupies, the work, oi course, being rotated through an angle of 90". \Vith this in view means is provided for rocking shaft 4-00 so as to move the gage from one side to the other of the work support. Accordingly gear segment 390 is termed with a pair of concave seats 406, JUS arranged to (EU-Operate with a pair of stops 410, 4-12 each secured for arcuate adjustment as by a bolt and slot connection 415; to a suitable part of the frame of the machine. Shat't ion is provided with a handie 4H- hy which it may be rocked and with an arm llti to which is anchtn'cd one end ()i a spring 4-18 the other end of which is anchored to the lrame ot the machine, the arrangement beingsuch that as the, handle -il-l-l rotated in a counter clockwise direction, as viewed in Fig. 9, the gear segments will be similarly rotated, shitting gage 384.- to the right. As soon as shat't 400 has thus been rotated suliiciently to move the axis ol spring 41s past the axis oi shaft 400, the spring completes the rotation of the shaft, snapping seat 4-06 into engagement with step 410.

As illustrated in Figs. 8 and 9, the work support 30:2 provided with a readily removable nail clinching bar 430, the left hand extremity of which, as shown in Fig. 8, is formed with an opening 432 arranged to slip over a pin iii-3 1 to prevent upward or lateral movement of the bar while its other end is provided with an opening 4.36 arranged to re ceive the upper end of a spring-pressed plunger 438 to prevent endwisc or lateral movement oil the bar. Thus by manually depressing plunger 4-38 the clinching bar may conveniently be rei'noved.

The abutment or gage bar 3386 (Figs. 10 and ll) is also preferably adjustable. As shown, gage bar 386 is provided with bearings tor a shaft 4.414 carrying a pair of pinions 457172 each meshing with a stationary rack 4A0. Shaft 44st provided with a hand wheel 446 by the rotation of which the gage may be adjusted. A pair of clamp bolts lit) are carried by the gage bar and have slotted connection with the frame of the machine so that; the gage bar may be clamped in adjusted position.

li desired, the machine may be arranged to insert staples instead of loose nails in which case the raceway may comprise a singie bar 45H down which the staples may slide, as illustrated in cross-section in Fig. 12.

To assist in holding the work upon work support Iitii'i, supplemental work support may be provided. As shown in Figs. 1 and 3. a rod 5th! is adjustaidy clamped in a sleeve not carried by column 122. this rod being provided at its right. hand end with a sleeve mm in which is adjustably clamped for vertical sliding movement a second rod 508, to the upper end of which is pivoted a lever me having a horizontal rod 512 clamped to its upper end. A lug 5H- t'ormed upon the lower end of lever old prevents its movement to the right ot the position indicated in Fig. itv will be apparent that if desired the lower portion ol' the work may be rested upon rod 5h. while its upper portion is held by work support Still.

As illnqrated in Fig. l the sliding head 2%; may be brought into position over either work support Itlt) or work support 302 aecording as the exigencies of the situation require. It, will be noted, moreover, that the machine of Fig. :2 is substantially the machine. o. Fig. l w: h the work support 300 eliminated. and tmek :lti and the various drive shafts shortened. the whole being carried upon a single column. Similarly a machine might be provided having only the work support 300. l'v'hcther one machine should include both work supports or whether separate machines would be mosteconomieal in any given case, would depend upon local conditions among which the quantity of work required to he done as related to the capacity of a single machine such as that oi Fig. l, or to the capacities of a pair ol machines. one provided with each kind ot work support, would be of; primary consideration. lt is conteml'ilatcd, moreover. that the number of trunks which could be nailed upon a single machine having a work support such as 3H2, as illustrated in Fig. 2. would be substantially greater than that ot a machine having only work support 2300 owing to the smaller amount of work in each trunk ot a character to be done upon that type oi work support. Accordingly a single machine. as shown in Fig. 2, might well take care ot the work from two machines each providetl only with a work support: of the character shown at 1300.
